My first post here. I am in the prep phase of my permanent layout. I have built a couple of layouts and have always used the massive amount of tubular track i've had on hand. This time around I'm going with Gargraves and Ross switches. I will be modeling a section of the Rathole division of the Southern railway. So I will Have some tunnels. I was planning on using my tubular track for the hidden areas inside the tunnels. Is there any pitfalls in doing this? Track height, connections etc... Also I plan on having a lot of lionel operating accessories. Could I use the Lionel activation and decoupling tracks with the Gargraves track? What would be the downside? I have a ton of tubular activation tracks and decouplers, trying to adhere to a budget, lol.
Thank you in advance
